MoonCraft MCS-1 1980 (Mazda, March parts)

We have a MoonCraft MCS-1 ( mooncraft special 1) in New Zealand, which we are currently restoring.

Would love some info about it.

Imported it from Japan in the early 1990's, I have seen a link to a Moon Craft Car the NZ/ Australian Driver Mike Thackwell drove, I also know this car was to do with the Grand Champions series at Fuji.
